Samsung has started rolling out the Android 4.1.1 Jelly Bean update for the Galaxy S III. The official firmware update comes after tons of unofficial firmware leaked over the last few weeks. In fact, the Jelly Bean sources for the I9305 variant of the Galaxy S3 also made an appearance on the Internet a few days ago.

The Jelly Bean update for the Galaxy S III brings an updated notification bar with expandable notifications, Project Butter for buttery smooth performance and UI interactions, Google Now, some minor UI changes, enhanced Face Unlock, and more. Samsung has also fixed some issues found in the previous Galaxy S III firmware along with updating some pre-installed apps including freeing up more RAM, replaced S Memo with S Note, new Camera and Gallery app, two different homescreen modes, and a bunch of other changes and tweaks.

As of now, Samsung is only rolling out the Jelly Bean update in Poland via its KIES software. The OTA update should not be far away, and a global roll-out should happen soon enough as well.
